Purpose: The present study was conducted to investigate whether the elution of the dyes from the circle contact lenses existed or not when rubbed with cotton swab. Methods: The change of lens surface was observed by scanning electron microscope when a total of seven kinds of circle contact lens were rubbed with cotton swab, and the dye elution was further compared when the lenses were soaked in multi-purpose solution in 20℃ and 36.5℃ for a week. Results: Five of a total of 7 circle contact lenses showed the dye elution from the front or the back surface of the lens when rubbed with cotton swabs, and existence of dye elution was varied depending on the type of contact lenses and different at the front and back surface even in the same lens. The tear-off of the pigmented portion by the rubbing was found through scanning electron microscopic observation when the dye elution existed. However, the dye was not eluted when the circle contact lenses was soaked in a multi-purpose solution in 20℃ or 36.5℃ for a week. Ingredient of colorant was not provided by the manufacturers in more than 50% of the circle contact lenses investigated for this study and the basic information such as the pigmentation method was provided inappropriately. Conclusions: In this study, the result was the dye elution from circle contact lenses was obtained when a physical force is applied thus, it may appear to contribute the development of circle contact lenses and safety of lens wear.
